CORNER-BLOCK FOR BEDSTEADS.

Specification of Letters Patent.

Application filed September 15, 1919. Serial No. 323,785.

To all whom it may concern:

Be it known that I, SAMUEL J. LAvnzzI, a citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvements in Corner-Blocks for Bedsteads, of which the following is a specification.

The object of my invention is to provide a simple and eiiicient construction of corner blocks made of sheet metal and adapted to take the place of the ordinary corner blocks made of castings. Such castings are open to manyobjections chief among which may be mentioned, first, the fact that inasmuch as they are rough castings and are not machined they do not fit properly with the end of the side rails and end rails with the result that such heads are frequently broken and repairs are expensive and sometimes impossible; and second, the fact that there is y no standard as to these corner blocks made of castings, that is standard either in size or character and consequently when a manufacturerlgoes out of business or discontinues any line of construction the repair parts are unobtainable and repairs are impossible.

My construction of corner block overcomes the several objections to the old form of blocks particularly because the same are indestructible and adapted to icooperate with the side rails and end rails in a manner so that they may be readily attached to and detached from thecorner block. 7

In the drawings Figure 1 is a plan view of one of the sheet metalpieces of which my corner block is composed, the same being shown in its flat form before bending to shape; Fig. 2 a corresponding View of the other piece composing my corner block; Fig.

3 a plan view of one of my corner blocks with adjacent ends of the side rail and end rail showing one of the bed posts, such post being either the upper left end one or the lower right end one; Fig. 4 a sectional elevation on the line 4-4 of Fig. 3; Fig. 5 asection on the line 5-5 of Fig. '3; Fig. 6 a sectional elevation of the corner block and post viewed from the outer side of the bed; Fig. 7 a section on the line 7-7 of Fig. 8; Fig. 8 a section on the line 8-8 of Fig. 7 Fig. 9 a sectional elevation on the line 9-9 of Fig.

Referring to the particular embodiment of my invention as herein shown, the corner block is formed of two pieces of sheet metal bent to shape and assembled together and then secured together in suitable manner as by welding, preferably at several points as hereinafter described. The two pieces of sheet metal are shown in Figs. .1 and 2 before they are bent to form at dotted lines indicating the lines of bending.

Referring first to the piece shown in Fig. 1 the same comprises a portion 1 which be comes a Vertical plate which is curved to conform to the outer surface of the bed post which is here of the cylindrical type as shown in Figs. 3 and 4:. This piece further comprises a'vertical side plate 2, a top plate 3 and a horizontal plate 4. When the piece is bent on the line 5 the "two plates 1 and 2 become at right angles to each other. Likewise when the piece is bent on the line 6 the top plate becomes at rightangles to the side plate 2. So also when the piece is bent on the line 7 the plate 1 becomes at right angles to the side plate 2 and parallel to thetop plate 3. The top plate is provided with an extension 8 having a. hole 9 for attachment of the end rail as hereinafter explained.

For attachment to the bed post the verti- Patented Apr. 26, 1921. s

cal plate 1 has holes 10 and 11 through which pass the bolts 12 and 18. For attachment of the side rails in amanner hereinafter explained the top plate 3 has a slot 12 to receive the squared or angular head of a fastening bolt and the plate 4 has a somewhat larger slot 13 to receive the lower end of such bolt.

Referring to Fig.2 the other piece comprises a vertical plate 14; adapted to fit against the plate 1, a vertical side plate 15,

extension 21. By bending on the line 22 this extension 21 becomes in line with and extends above the plate 14. This extension is provided with a hole 23 adapted to register with the hole 10.

The plate 1 1 is provided with a hole 2 1- adapted to register with the hole 11 of the plate 1. The top plate 16 is provided with a slot 25 adapted to register with the slot 12. The plate 17 is provided with a slot 26 adapted to register with the slot 13. The

side plate 15 has a tongue 27 punched out therefrom and bent at right angles thereto along the line 28.

When the two pieces are bent in the manner above described the same are assembled together to form the corner block. In this assembly the plates 14 and 21 fit against the vertical plate 1 and are secured thereto preferably by spot welding. The top plate 16 is positioned below and against the top plate 3 and the bottom plate 17 fits on top of the bottom plate 4.. The corner block structure may therefore be said to consist of a vertical plate or plates adapted to be secured to the bed post, two parallel plates at substantially right angles thereto such as the plates 2 and 15, these plates terminating at their outer ones in a casing rectangular in cross-section and composed of double thicknesses of sheet metal at top and bottom by reason of the plates 3 and 16 at the top, and l and 17 at the bottom, and with single thickness of side wall consisting of the two parallel vertical plates 2 and 15 or rather the other end portions of these plates. This casing is adapted to receive an end of a side rail in a manner hereinafter described. An end of an end rail is adapted to be received by the two right angled extensions 8 and 27 to which such end rail is secured by means of the bolts or rivets 29 and 30 passing through the holes 9 and 31 respectively as clearly shown in Figs. 3, 4 and 5.

The two pieces comprising the corner block are preferably welded together not only along their vertical plates 1 and 14 as described but also along the meeting edges of the plates 15 and 3 asindicated at 82 in Figs. 3 and 7,. and also along the free edge of the bottom plate 1 where it meets the corner or bend between the side plate 15 and bottom plates 17, that is along the bending line 20. Such point of welding is at the point or line 33 as indicated in Fig. 7.

- Describing the fastening means between a side rail and a corner block, the same consists of a peculiarly constructed bolt and slee'vethereon cooperating in the bolt holes in the corner block described. This bolt 3% has an angular head 35 at its upper end. adapted to be received in the slots 12 and and to slide laterally therein. a The shank of this bolt is surrounded at a point within said casing by a sleeve 36 which together with the lower end. of the bolt extends through the larger slots 13 and 26. A washer 37 is preferably provided at the upper end of the sleeve 36. A suitable nut such as the thumb nut 38 screws onto the lower end of the bolt, and against the lower end of the sleeve the boltis preferably provided with a flange 39 to retain the nut thereon. The side rail 40 which is of the angle bar type, is provided with peculiarly shaped ends, each end being substantially arrow shape with inclined outer ends 41 and opposite lateral recesses l2. The construc-* tion is such that when the end of the side rail is inserted into the casing of the corner block one of these inclined ends 41 will engage a side of the bolt or rather its sleeve 36 whereupon such bolt will be automatically shifted laterally to an end of the slot whereupon the rail is inserted to its full distance as shown in Fig. 8, after which the bolt is slipped back laterally into normal position sons to be received within one of the recesses 12, whereupon the nut 38 is tightened and the corner block and rail thereby clamped firmly in position. The side rails are thus detachable from the corner block but the end rails 4-8 arepreferably permanently secured thereto by the rivets as already described.
